Armadillo vs Keystone Gray
Both are Sherwin-Williams colors. Both sit in the greige-grey family, which is useful context if you're narrowing within a single hue direction. With LRVs of 29 and 29, they'll behave almost identically in terms of how much light they reflect back into a room. They share a warm quality — useful to know if you're layering them in the same space. At ΔE 4.0, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Armadillo vs Keystone Gray in Real Spaces
3 real rooms side by side. Armadillo and Keystone Gray are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. The distinction reads clearly at room scale, making the choice between them concrete.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

Armadillo vs Keystone Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Armadillo on one side and Keystone Gray on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
